Trolley-wire hanger



IINTTED l STATES IVILLIAM S. III-SINGER, OF BANTAM, OHIO, ASSIGNOR TO THE KISINGER-ISON COMPANY, OF CINCINNATI, OHIO.

SPECIFICATION forming part of Letters Fatent No. 569,838, dated October 13, 1896.

Application filed February S, 1896. Serial No. 578,500. (No model.)

To all whom t 71u01/ concern:

Be it known that I, WILLIAM S. KIsINeER, a citizen of the United States, residing at Bantam, in the county of Clermont and State of Ohio, have invented certain new and useful Improvements in Trolley-fire Hangers 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings,

1o which form a part of this specification.

This invention relates to those insulatinghangers used for supporting line-wires of underrunnin g trolleys; and my improvement comprises a novel combination of devices whcrewith a line-wire holder is very readily and yet perfectly and securely coupled to the yoke, the details of said combination being hereinafter more fully described, and then pointed out in theclaims.

In the annexed drawings, Figure lis a side elevation of a yoke and line-wire holder separated from each other, the yoke-hub being sectioned and said holder shown in the proper position for engaging therewith. Fig. 2 is a vertical section of the yoke, the holder being coupled thereto and turned around to the proper position for supporting the line-wire. Fig. 3 is a plan of the under side of the yokehub and its attachments, the holder being omitted and its position indicated by dotted lines. Fig. 4 is a plan of said holder detached from the yoke. Fig. 5 is an enlarged vertical section of the coupled yoke and holder, a locking device being shown to prevent retrograde turning of the holder-stem. Fig. 6 is an enlarged detail view.

A represents the central portion or hub of a trolley-wire hanger, and B B are arms proj ecting from said hub and having perforations l) h', to which the span-wires are attached in the usual manner. These arms and hub constitute the yoke of the device, and the hub is bored vertically at C to admit an annular non-conducting filling D, the under surface of which has a drip-groove d, that prevents water running in toward the center of said filling. Again, this Iillingis bored vertically, as at E, to admit the cylindrical shank F of a cap G, that rests upon the yoke and is so shaped at top as to shed Water away from the hub-bore C.

TRO LLEY-WIRE HANG ER.

PATENT OEETCE.

The lower portion of shank F is chambered out at Il, and the entrance to said chamber has a pair of diametrically opposite bearings h h, whose upper surfaces are inclined, as more clearly seen in Fig. 5. Furthermore, these bearings are on the sides of the chamber, and a line drawn through the center of the arms B B' will pass also through the center of said bearings, the location of the latter 6o being more clearly seen in Fig. 3.

I is any approved form of line-wire holder, and t' are clips for retaining the wire in place.

J is a cylindrical stem projecting upwardly from said holder and armed with a pair of lugs jj, whose under surfaces are inclined to exert a wedging action against the bearings t 7L'.

K is a horizontal circular flange of the holder, the diameter of said iiange bein g about 7o equal to the inner diameter of the drip-groove d, as seen in Fig. 2.

In putting up my improved hanger the spanwires, that cross the streets, are fastened to the poles and then to the arms B B/ in the usual way, after which act the non-conducting filling D d and cap G F are inserted Within the hub of the yoke. The trolley-wire holder I is then brought in line with said arms, as seen in Fig. l, so as to enable its stem .I to 8o be passed up into the chamber II of said cap, which is readily accomplished, because the lateral lugs jj' of said stem are now in line with the interdental spaces between the bearings h h. The holder is then turned around 8 5 at a right angle to its former position, as seen in Fig. 2, the result being to cause said lugs to wedge against said bearings and thereby couple the holder to the yoke in a very secure and expeditious manner and without using 9o special tools of any kind. The trolley-wire is next applied to the holder I in the usual way, and as said wire runs at a right angle with reference to the span-wires the natural tendency of this strain is to keep the holder coupled to the yoke; but to prevent the possibility of any displacement some suitable locking device may be used, a simple form thereof being seen in Fig. 5. Here a split spring-key L is passed up through a suitable roo opening in the flange K, and bears against the larger end of either one of the bearings 71, or 7L. By simply withdrawing this key the steinJ can be so turned as to disengage its lugs from the bearings and then be pulled directly out of the ehambered shank.

Itis evident that the cap G F must be insulated from the yoke in any suitable Way, but preferably byenveloping it in hard rubber, as indicated in the drawings by the thick black lines. As seen in Fig. 1, this cap may be locked against turning by a lug g, entering a notch b" of the yoke-hub.

Fig. G shows that the lugj j may be undercut inwardly, or toward the stem J. Finally, the openings between the bearin gs 7i, 7L need not be located in any special position when the keyL or an equivalent of the same is used.

I claim as my invention l. The combination, in a trolley Wire hanger, of a yoke; an insulated member applied thereto, and having a vertical chamber with a pair of inclined bearings at its lower end; and a line-Wire holder provided with a pair of inclined lugs that engage over said bearings, for the purpose described.

The combination, in a trolley Wire hanger, of a yoke; an insulated member F applied thereto, and having a vertical ehani= ber II with a pair of inclined bearings la h', at its lower end 5 a line-wire holder l having a pair of inclined lugsjjj, that engage over said bearings; and a locking device se applied to said member F as to prevent retrograde turning oi' said stein, in the manner herein described.

The combination, in a trolley wire hauger, of a yoke; an insulated member F applied thereto, and having a vertical cha1nber ll, with a pair of inclined bearings 7i, 71,', at its lower end; a line-wire holder I having a pair of inclined lugs j, j', that engage over said bearings; a perforation in said \vi1e holder; and a split spring-key L that passes through said perforation and bears against the larger end of either one ot' said bearings z, or 71.', all as herein described, and for the purpose stated.

In testimony whereof I allix my signature in presence of two witnesses. VILLAM. S. KISINGER.
